NTP (Network Time Protocol) server
Synchronizes the date and time of computers and servers on a network, based on Coordinated
Universal Time (UTC).
parity
Data created in volumes with RAID 5 protection that’s used to reconstruct files if one of the disk
drives in the server fails. See also “RAID 5”.
private share
A folder that is accessible only to users with permission granted by the share’s owner.
RAID
Redundant Array of Independent Disks. A technology that combines disk drives together for
improved performance and fault tolerance (the ability to withstand the failure of a disk drive).
RAID 0
RAID 1
RAID 5
A level of RAID protection. A volume with RAID 5 is built from a minimum of three disk drives,
and uses data striping and parity data to provide redundancy. (Parity is extra information that’s
used to re-create data if a disk drive fails. In volumes with RAID 5, parity data is striped evenly
across the disk drives with the stored data.) Parity data provides data protection, and striping
improves performance. See also “stripe”.
RAID 10
A level of RAID protection. A volume with RAID 10 is built from two or more equal-sized RAID 1
volumes. Data in a volume with RAID 10 is both striped and mirrored. Mirroring provides data
protection, and striping improves performance. See also “mirror”, and “stripe”.
remote access
Access to the server from a computer that is not on your local network. For instance, accessing
the server from a client’s computer, over the Internet, is remote access.
Remote access can also refer to shutting down or resetting the server using BlackArmor Man-
ager instead of physically pressing the Power button. See also “local access”.
replication
The process where an exact copy of the data on your BlackArmor server is created and continu-
ously maintained on a second BlackArmor server using a permanent network connection. Con-
tinuous backups provide the best protection against data or device loss, especially if the second
